ABSTRACT: The present study included 50 Cases, Group-1- 25 Cases, underwent Temporal Sclera incision phacoemulsification, Group-2: 25 Cases underwent temporal clear corneal incision phacoemulsification. Out of this majority of the cases with scleral incision Group showed an surgically induced astigmatism of 0.5 D(56%), in clear corneal group 40% showed 0.5 D and 32% showed 0.75 D of Surgically induced astigmatism. The mean surgically induced astigmatism in scleral incision Group was 0.55?0.28 and in clear corneal group 0.69?0.25. In both the cases there is decrease in pre-operative against the rule astigmatism to Post–Operative against the rule astigmatism and an increase in with the rule astigmatism from Pre-Operative to Post–Operative period, but this is seen more with clear corneal incision group compared to scleral incision group.
